My invention relateslto the class of devices employed forregulating the admission of air through open windows, and an object of my invention, among others, is, the provision of adevice of this class that isportable, that maybe readily aflixed to and detached from a windowcasing orframe, and especially one that maybe pla cedin compact form for carrying purposes. Q v One form/of, a shield embodying my in.- vention and inthe construction andluseof which the objects hereinfset out, as well as others,' may be attained, is illustrated inthe accompanyingdrawings,in which fFigurel isa'iview ofa portion of a window frame showingmy improved shield attached thereto, l l' v Figure 2 i a view in section one plane denoted bythe dotted line ofFignre' 1 Y'FigureB.

Although it is desirable to have open winfdows' in sleeping roomsan objection is often present, especially-Fin the case of persons traveling, "in opening 'the' windows in the rooms of hotels and similar places,ifor the 15:45 reason that fdraughts are" created and no means are readily at-hand to prevent such draughts, and it'is a purpose of my present invention to provide means whereby windo'ws may be open and whereby draughts V'- through such openings may be prevented,

my improveddevice being so constructed cur ain. fixt res;

"ends of the arms Of a retaining bracket "23 1 tent and the frames. '14 "being securedto the that it may be readily placed in compact form if forcarrying purposes. r r 'Such a device is illustratedin the accompanying drawings in which the numeral 10 V indicates'the side parts of a window frame, 55 and 11 a window sill in which a sash comprising a; bottom rail 12fand side rails 13 is mounted for vertical sliding movement. My improved shield, in that form of the devices shown in'Figures land 2 comprises a bracket including aU-shaped frame 14 that is adapted toreceive between its'branches the b ottoni rail 12 of a window sash, a clamp screw 15 in-oneof said branches being adapted for clamping theframe to said rail, and as shown in- Figure 2.. Al arm 16 is also included in the bracket structure, this, arm having a roller frame clam 17 comprising a threaded stud and a thumg-nutbymeans of which a roller frame 18 may be adjustably supported on said arm.)

" Said roller name has roller 1 supporting arms 19 in which a roller 20 is rotatably mounted, and a flexible shield 21, preferably of canvas or similar material is wound upon the roll and is'adapted to be extended thelefrom orto be wound thereon when the "rollis rotated This roller may be a spring roller if desired, that is a roller having a sp ng that will aut mat al y rotat i to indup 'theishie dii desired;- i The ends of herol e may bejreme ab' yfl placedn slo s extending inwardi nemi the ends of the arms 19 ina manne common to The. free end of t e shield is pro ided- ,withcatches for the purpose er securingthe shieldin an extended condition across the "window frame, 11.1 asatisfactory construction 7 this, catch being in the form of a stifiener 22 located a sheathfor ned in the end Of the shield th prejecting ends o t ifener comprising the catches that are engaged within slots. extending inwardly from the 'iraine' ii i 1 i I 7 A The o oerati.on will be readily'understood, the window ei gvrei e to the desired exsubstantia y. dup ic of hefb 'aeke Or bottom rail 12 of the sash with the frame 18 in position and which may be placed at any desired angle by means of the clamp 17. The shield 21 is then extended to the opposite side of the window frame and the catches are engaged with the bracket 23, thus effectually preventing air currents directly into the room through the open window, such currents being deflected upwardly by the shield 21, which, as hereinbefore stated, may be placed at any angle desired.

In the structure shown in Figure 3 the parts are all the same as hereinabove described, with the exception of the frame for securing the device in place. This frame 24: is so formed that it may be engaged with the projecting edge 25 of the window sill, instead of with the window sash, this ap plying to the frame at each end of the shield.

Inthe structure shown in Figures 4 and 5 the roller supporting members are the same as in the structures hereinbefore described with the exception that each roller supporting frame 26 has an arm 27 to which the frame is clamped as by a thumb nut 28. The arm 2'? has a clamp 29 for securing it to a supporting rod 30 comprising two members joined by a threaded stud 31 engaged with said members by threads extending in opposite directions whereby the members of the rod may be forced apart to press the bases 32 thereof into contact with the inner surface of the sides 10 of the window frame.

The structure shown in Figure 6 is very similar to that shown in Figures 4 and 5, the roller supporting frames being omitted as not necessary to an understanding of this part of the device. In this structure the supporting rod comprises two members 33-34 that are telescoped one within the other, the member 33 having its end provided with a slot to form a clamp 35 for securing the two members together in any position of lengthwise adjustment. y

In the structure shown in Figure 7 the roller supporting brackets are the same as hereinbefore described, but with the exception. that supporting arms 36 are provided with slots for the reception of studs 37 projecting from pivots of a lazytong structure 38 of old and well known construction and which-is clamped to hold it in any position by means of the studs 37 and thumb nuts 39 thereon.

It will be noted that this structure may be extended to press the bases 40 into close contact with the sides 10 of the window frame and thereby support the structure as whole.

In that form of the device shownin Figures 8 and 9 the roller supporting brackets are the same as hereinbefore described, but the supports therefor comprise a system of toggle levers pivotally united, two members a l-42 of such structure being provided with slots and a clamp stud and clamp nut 43 for securing the parts together.

In the use of this device the members 41 and 42 are adjusted so that the lever structure will be slightly longer than the space between the sides 10 of the window frame. This will enable the structure to be swung from the position shown in Figure 9 to the position shown in Figure 8 and thereby secure the device firmly in place and in a manner that will be readily understood.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.
